Design of Seaplanes
APPENDIX C3: Design of Seaplanes This appendix is a part of the book General Aviation Aircraft Design: Applied Methods and Procedures by Snorri Gudmundsson, published by Elsevier, Inc. The book is available through various bookstores and online retailers, such as www.elsevier.com, www.amazon.com, and many others. The purpose of the appendices denoted by C1 through C5 is to provide additional information on the design of selected aircraft configurations, beyond what is possible in the main part of Chapter 4, Aircraft Conceptual Layout. Some of the information is intended for the novice engineer, but other is advanced and well beyond what is possible to present in undergraduate design classes. This way, the appendices can serve as a refresher material for the experienced aircraft designer, while introducing new material to the student. Additionally, many helpful design philosophies are presented in the text. Since this appendix is offered online rather than in the actual book, it is possible to revise it regularly and both add to the information and new types of aircraft. The following appendices are offered: C1 – Design of Conventional Aircraft C2 – Design of Canard Aircraft C3 – Design of Seaplanes (this appendix) C4 – Design of Sailplanes C5 – Design of Unusual Configurations Figure C3-1: A Lake LA-250 Renegade, shown here during climb after T-O, is a popular option for amphibious aircraft. The large deflected flap on the horizontal tail is a hydraulically actuated trim tab used for slow speed operations only. It trims out the thrust effect of the highly mounted piston-propeller, improving its handling. -

WW2 /Emergency Stories from Clare Clare In
Clare in WW2 - The Emergency - WW2 /Emergency Stories from Clare Stories from Clare D Day 1944 - The 2nd US Rangers By Ger Browne The aim of this project is to find out how many men and women from Clare took part in WW2, and the effect of the war on Clare. It is hoped that an extension will be added to the Great War Memorial in Ennis that will include the names of the Clare War Dead from WW2 / The Emergency. At the moment we know that 86 died from Clare as well as in Clare. I would like to thank Keir McNamara, and his late father Peadar McNamara for all their research on WW1 and WW2. Eric Shaw, who has been providing me with amazing WW1 and WW2 information for years, and all the following who have helped make this project possible. Paddy Waldron, The Local Studies Centre, Peter Beirne, Brian Doyle, Guss O’Halloran, Sean Glennon, Jim Molohan, Joe Ó Muircheartaigh, Eddie Lough, Local Parish Booklets, The Clare Champion and The Clare People. I have also named the sources, with many of the names below. I thank them all.

Episode 6, NC-4: First Across the Atlantic, Pensacola, Florida and Hammondsport, NY
Episode 6, NC-4: First Across the Atlantic, Pensacola, Florida and Hammondsport, NY Elyse Luray: Our first story examines a swatch of fabric which may be from one of history’s most forgotten milestones: the world's first transatlantic flight. May 17th, 1919. The Portuguese Azores. Men in whaling ships watched the sea for their prey, harpoons at the ready. But on this morning, they make an unexpected and otherworldly sighting. A huge gray flying machine emerges from the fog, making a roar unlike anything they have ever heard before. Six American airmen ride 20,000 pounds of wood, metal, fabric and fuel, and plunge gently into the bay, ending the flight of the NC-4. It was journey many had thought impossible. For the first time, men had flown from America to Europe, crossing the vast Atlantic Ocean. But strangely, while their voyage was eight years before Charles Lindbergh's flight, few Americans have ever heard of the NC-4. Almost 90 years later, a woman from Saratoga, California, has an unusual family heirloom that she believes was a part of this milestone in aviation history. I'm Elyse Luray and I’m on my way to meet Shelly and hear her story. Hi. Shelly: Hi Elyse. Elyse: Nice to meet you. Shelly: Come on in. Elyse: So is this something that has always been in your family? Shelly: Yeah. It was passed down from my grandparents. Here it is. Elyse: Okay. So this is the fabric. Wow! It's in wonderful condition. Shelly: Yeah, it's been in the envelope for years and years. -
Coastal Command in the Second World War
AIR POWER REVIEW VOL 21 NO 1 COASTAL COMMAND IN THE SECOND WORLD WAR By Professor John Buckley Biography: John Buckley is Professor of Military History at the University of Wolverhampton, UK. His books include The RAF and Trade Defence 1919-1945 (1995), Air Power in the Age of Total War (1999) and Monty’s Men: The British Army 1944-5 (2013). His history of the RAF (co-authored with Paul Beaver) will be published by Oxford University Press in 2018. Abstract: From 1939 to 1945 RAF Coastal Command played a crucial role in maintaining Britain’s maritime communications, thus securing the United Kingdom’s ability to wage war against the Axis powers in Europe. Its primary role was in confronting the German U-boat menace, particularly in the 1940-41 period when Britain came closest to losing the Battle of the Atlantic and with it the war. The importance of air power in the war against the U-boat was amply demonstrated when the closing of the Mid-Atlantic Air Gap in 1943 by Coastal Command aircraft effectively brought victory in the Atlantic campaign. Coastal Command also played a vital role in combating the German surface navy and, in the later stages of the war, in attacking Germany’s maritime links with Scandinavia.

[Later their counterpart G-AETV Coriolanus was scrapped at Rose Bay.] Meanwhile, the Poole stalwarts G-AFKZ Cathay and G-AFCT Champion finished the routine weekly service to Lisbon. Also, G-ADUW Castor wound up the last remaining easterly section of the Horseshoe service between Calcutta & Cairo.

Maritime Patrol Aviation: 90 Years of Continuing Innovation
J. F. KEANE AND C. A. EASTERLING Maritime Patrol Aviation: 90 Years of Continuing Innovation John F. Keane and CAPT C. Alan Easterling, USN Since its beginnings in 1912, maritime patrol aviation has recognized the importance of long-range, persistent, and armed intelligence, surveillance, and reconnaissance in sup- port of operations afl oat and ashore. Throughout its history, it has demonstrated the fl ex- ibility to respond to changing threats, environments, and missions. The need for increased range and payload to counter submarine and surface threats would dictate aircraft opera- tional requirements as early as 1917. As maritime patrol transitioned from fl ying boats to land-based aircraft, both its mission set and areas of operation expanded, requiring further developments to accommodate advanced sensor and weapons systems. Tomorrow’s squad- rons will possess capabilities far beyond the imaginations of the early pioneers, but the mis- sion will remain essentially the same—to quench the battle force commander’s increasing demand for over-the-horizon situational awareness.

A Compelling Swansong Aquila, Artop and TEAL
Poole Flying Boats Celebration (Charity No.1123274) PFBC Archive: Our Charity is committed to developing & maintaining its Public-Access Archive… For the purpose of this website a brief selection of items together with information have been provided where references in blue indicate further material is available. Á Part Twelve: A Compelling Swansong for the Flying Boats… ‘Aquila, Artop & TEAL’ © PFBC Poole Flying Boats Celebration acknowledges the significant contribution which Aquila Airways paid to the History of the UK’s Flying Boat services during some 10 years of its operations from 18th. May 1948, until 30th. September 1958. Through his entrepreneurial vision & passion for Flying Boats, former RAF Wing Commander - Barry T. Aikman DFC , with the dedication of his airline staff, a marvellous swansong was added to this history during that period when the last vestiges of travel by the glorious Flying Boats were being wound-up across the world, with new airports for landplanes. As with some of the relationship of Poole to this history, there were links with Aquila which at first glance seem slender. However, upon closer examination the research to support PFBC’s public-access Archive, coupled with very important information generously provided for the Charity by an Hon. Life Member - Norman Hull (formerly of Aquila Airways), has highlighted various intrinsic connections, which now justify the inclusion of Aquila within a PFBC Website section. The involvement of Aquila through its batch of Hythe Class Flying Boats has a certain resonance for the sterling service that the Hythes had when at Poole in operating with RAF Transport Command, - and with BOAC through to April 1948.
